Changes in |csit-release|
-------------------------
-No code changes apart from bug fixes.
+#. **DPDK release version change**
+
+ - |csit-release| tested DPDK-18.05, as used by |vpp-release|.
+
+#. **DPDK performance tests**
+
+ - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
+ configurable trial duration and number of consecutive executions.
+ Coverage of MRR tests has been extended across more test
+ scenarios. MRR tests are used for continuous performance trending
+ and for comparison between DPDK releases.
+
+ - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
+ for all NDR and PDR throughput tests. All tests that previously
+ used binary search got converted to MLRsearch. Coverage of NDR/PDR
+ tests has been extended across more test scenarios.
+
+ - **2-Node Tests**: A new set of 2-node tests covering DPDK Testpmd
+ and L3fwd, running on new Xeon Skylake testbeds.
+
+ - **More NICs**: Increased coverage of NIC models tested: Intel-
+ xxv710-da2, Intel-x710-da4.
+
+ - **Generated tests**: Simplified and unified test structure, semi-
+ autogenerated by generator script. Test generator is currently
+ able to create test combinations with various frame size and
+ cores combinations. All existing test cases were converted to new
+ format.
+
+#. **Presentation and Analytics Layer**
+
+ - **Performance trending**: Added continuous performance trending with
+ anomaly detection and analysis for DPDK.
Performance Changes
-------------------
-Relative performance changes in measured packet throughput in |csit-release|
-are calculated against the results from |csit-release-1|
-report. Listed mean and standard deviation values are computed based on
-a series of the same tests executed against respective VPP releases to
-verify test results repeatability, with percentage change calculated for
-mean values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatability vary between the test cases.
+Relative performance changes in measured NDR, PDR and MRR packet
+throughput in |csit-release| are calculated against the test results
+from |csit-release-1| report, for tests running on 3-Node Intel Xeon
+Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only)
+configurations.
